Investigação das contribuições de emissões atmosféricos causados por veículos automotores leves: Estudo de caso UTFPR- LD

Abstract

In recent decades there has been an exponential increase in the national fleet of light vehicles, due to their greater practicality and convenience. Advances in technology have made engines more efficient, but as the national fleet grows every year, it is important to have a better idea of the pollutants emitted by vehicles, which can pose a risk to health. This study complements previous studies carried out at the Federal Technological University of Paraná - Londrina Campus. The study is based on work carried out at the University by former graduates on the same subject, with information on vehicles registered by students, teachers and staff who visit the University on a daily basis, this is used to measure emissions for each vehicle individually using INMETRO's PBE tables for Non-Methane Hydrocarbons (NHCM), Nitrogen Oxides (NOx), Carbon Monoxide (CO) and Carbon Dioxide (CO2) (from fossil fuels - gasoline) in g/km, the latter in Kg/km. For the 241 vehicles validated, the CHEVROLET, FIAT, VOLKSWAGEN, RENAULT AND PEUGOET models are the biggest contributors to daily emissions of atmospheric pollutants. Taking all the vehicles into account, the daily totals are 72.769 g of NHCM, 1190.341 g of CO, 104.929 of NOx and 349.707 Kg of CO2 (from fossil fuels - gasoline). In conclusion, we encourage the use of more sustainable means of transportation and further research into the emission values of atmospheric pollutants.
